Firestreamer is a software that allows you to use your Digital Video camcorder or VCR as a reliable computer data storage device. You can store up to 15 Gigabytes of files and folders to a Mini-DV cassette, or more with the built-in compression enabled. Utilizing a patent-pending technology, Firestreamer makes your DV recorder appear as a regular tape drive to other applications running on your computer, so that you can use the powerful Backup Utility, which comes with your Windows operating system, to back up and restore your files and folders to and from videotape. The backup and restore are fully automated, as with a normal tape drive. You only need to change tape cassettes when prompted.
